sudo-rs – memory safe implementation of sudo and su

sudo-rs is a safety oriented and memory safe implementation of sudo and su written in Rust. It’s an independent implementation, but it incorporates documentation and Rust translations of code from sudo.

sudo-rs supports less functionality than sudo. Some of this is by design. In most cases you will get a clear error if you try something that is not supported (e.g. use a configuration flag or command line option that is not implemented).

Some parts of the original sudo are explicitly not in scope. Sudo has a large and rich history and some of the features available in the original sudo implementation are largely unused or only available for legacy platforms. In order to determine which features make it the developrs both consider whether the feature is relevant for modern systems, and whether it will receive at very least decent usage. Finally, of course, a feature should not compromise the safety of the whole program.

sudo-rs has been audited twice: an audit of version 0.2.0 was performed in August 2023, and a second audit of version 0.2.8 in August 2025.

This is free and open source software.
